I'm from Oregon, hope I do this right. I've done tons of research on radar detectors, used to have an older sleek model, talking Cobra I thought it was ok, got me out of few tickets, but not enough lol, then it broke in a near fatal car accident. I have a habit of a lead foot I need a new one sadly can't really go over 160.00, was gonna buy another Cobra, but their so bulky now. I've been on all the cool sites so far I like Whistler, but I need to be sure..I'm bit confused with few things as Whistler doesn't have the Vg-2 alert like the Cobras I won't know when I'm being detected by another detector RDD is this needed and just what is Spectre I Immunity Provides RDD is this for cloaking other RDD on police radar or both? I was told that the Whistlers are hard to be detected by police radar is this true anyone know? I just now looked up that Oregon most parts still use X-band and a lot of your tests prove that Whistler on the X-band far alerted over Cobra think I just gave self the answer to my search, but really still appreciate any input and also the difference in the Whistler models like the PRO-78 SE, XTR-690 SE, or XTR-695 SE aside from the features, do they test any better in alerting on the diff models, same brand?..Thanks!
